    • A dosage device particularly for gravimetric mixers, which comprises:

      -- a first hollow body (14), which is provided in an upward region with a loading opening (15) that is arranged below the outlet (16) of a corresponding hopper (11) and, in a downward region, with an unloading opening (17) that is arranged above a weighing tank (18), in which there is
      -- a second body (19), associated with a corresponding crank system (34, 35, 36) and movable alternately from a position (15) for loading to a position (17) for unloading granules (22) from a pocket (20) formed within its perimetric outline. The first and second bodies (14, 19) provide a coupling by virtue of which only the granules (22) contained within the volume of the pocket (20) are conveyed between the loading and unloading positions.
    • 一种特别用于重力混合器的剂量装置,包括:第一中空体(14),其设置在向上区域中,其具有布置在相应料斗(11)的出口(16)下方的装载开口(15)和 在向下区域中,具有布置在称重罐(18)上方的卸载开口(17),其中存在与相应的曲柄系统(34,35,36)相关联的第二主体(19),并且可移动 交替地从用于装载的位置(15)到用于从形成在其周边轮廓内的凹穴(20)卸载颗粒(22)的位置(17)。 第一和第二主体(14,19)提供联接,借助于该联接器,只有包含在袋(20)的体积内的颗粒(22)在装载和卸载位置之间被输送。
